Tool display rack having holding and rotation test functions

ABSTRACT

A tool display rack includes a main body, a mounting portion mounted on the main body to allow passage of the drive stud of the tool and having a peripheral wall provided with a plurality of elastic locking portions urged on a peripheral wall of the drive stud, and a pressing member pivotally mounted on the main body and urged on the neck portion. Thus, the locking portions are urged on the peripheral wall of the drive stud of the tool to retain the drive stud of the tool in the retaining portions closely, so that the drive stud of the tool is secured on the mounting portion of the tool display rack rigidly and stably.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a tool display rack, and moreparticularly to a tool display rack having holding and rotation testfunctions.

2. Description of the Related Art

A conventional tool display rack in accordance with the prior art shownin FIGS. 8 and 9 comprises a main body 40 formed with a circular hole 41for mounting the square drive stud 310 of the drive head 31 of a wrench30, and a pressing member 42 secured on the main body 40 and urged onthe neck portion of the wrench 30. However, the wrench 30 cannot berotated relative to the main body 40 of the tool display rack to testthe rotation angle of the drive stud 310 of the wrench 30.

Another conventional tool display rack in accordance with the prior artshown in FIGS. 10 and 11 comprises a main body 40 formed with a squarehole 43 for mounting the square drive stud 310 of the drive head 31 ofthe wrench 30. Thus, the square drive stud 310 of the wrench 30 ismounted in the square hole 43 of the main body 40, and the wrench 30 isrotated relative to the main body 40 of the tool display rack to testthe rotation angle of the drive stud 310 of the wrench 30. However, thesquare hole 43 of the main body 40 is larger than the drive stud 310 ofthe wrench 30, so that the rotation angle of the drive stud 310 of thewrench 30 is not tested exactly.

Another conventional tool display rack in accordance with the prior artshown in FIGS. 12-14 comprises a main body 40 formed with a circularhole 41, and a locking member 50 extended through the drive head 31A ofa wrench 30A and having a first end formed with a hexagonal positioningportion 52 secured in the drive head 31A of the wrench 30A and a secondend formed with a locking hook 51 extended through the circular hole 41and locked on a bottom of the main body 40 to secure the drive head 31Aof the wrench 30A on the main body 40. In such a manner, the hexagonalpositioning portion 52 of the locking member 50 is secured in the drivehead 31A of the wrench 30A, and the wrench 30A is rotated relative tothe main body 40 of the tool display rack to test the rotation angle ofthe ratchet wheel 32A of the drive head 31A of the wrench 30A. However,the tool display rack needs to provide a locking member 50, so that thetool display rack has a complicated construction, thereby increasingcosts of fabrication. In addition, the locking hook 51 of the lockingmember 50 cannot hold the main body 40 closely, so that the lockingmember 50 is easily rotated with the drive head 31A of the wrench 30A,thereby decreasing the testing precision.

DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings and initially to FIGS. 1-6, a tool displayrack 20 in accordance with a first embodiment of the present inventionis used for mounting a tool 10. The tool 10 has a drive head 11 and aneck portion 12. The drive head 11 of the tool 10 has a square drivestud 110.

The tool display rack comprises a main body 21, a mounting portion 211mounted on the main body 21 to allow passage of the drive stud 110 ofthe tool 10 and having a peripheral wall provided with a plurality ofelastic locking 1 portions 212 urged on a peripheral wall of the drivestud 110 of the tool 10, and a pressing member 22 pivotally mounted onthe main body 21 and urged on the neck portion 12 of the tool 10.

The main body 21 has a first end formed with a hanging portion 210 forhanging the main body 21. The mounting portion 211 is mounted on amediate portion of the main body 21 and is preferably a through hole.Preferably, the main body 21 is integrally formed with the mountingportion 211.

Preferably, the mounting portion 211 is integrally formed with thelocking portions 212 which are extended radially inward therefrom. Inaddition, the peripheral wall of the mounting portion 211 is providedwith a plurality of recessed retaining portions 213 mounted between thelocking portions 212. Preferably, the mounting portion 211 is integrallyformed with the retaining portions 213.

As shown in FIGS. 3, 4 and 4A, when the drive stud 110 of the tool 10 isinserted into the mounting portion 211 of the tool display rack 20, thelocking portions 212 are urged on the peripheral wall of the drive stud110 of the tool 10 to retain the drive stud 110 of the tool 10 in theretaining portions 213 closely, so that the drive stud 110 of the tool10 is secured on the mounting portion 211 and cannot be rotated relativeto the main body 21 of the tool display rack 20.

As shown in FIGS. 2 and 5, the pressing member 22 is pivotally mountedon a second end of the main body 21 and has an inside formed with apassage 220 to allow passage of the neck portion 12 of the tool 10.Preferably, the passage 220 of the pressing member 22 has a side havingtwo ends each formed with an oblique limit portion 221 to limit afurther movement of the neck portion 12 of the tool 10.

In such a manner, the neck portion 12 of the tool 10 is movable in thepassage 220 of the pressing member 22 between the limit portions 221 ofthe passage 220, so that the drive head 11 of the tool 10 is rotatedrelative to the main body 21 of the tool display rack 20 to test therotation angle of the drive stud 110 of the tool 10.

As shown in FIG. 6, each of the locking portions 212 has a reduced neckportion to enhance the elasticity of each of the locking portions 212.

Accordingly, the main body 21 of the tool display rack 20 is integrallyformed with the mounting portion 211, the locking portions 212 and theretaining portions 213, so that the tool display rack 20 has asimplified construction, thereby decreasing costs of fabrication. Inaddition, the locking portions 212 are urged on the peripheral wall ofthe drive stud 110 of the tool 10 to retain the drive stud 110 of thetool 10 in the retaining portions 213 closely, so that the drive stud110 of the tool 10 is secured on the mounting portion 211 of the tooldisplay rack 20 rigidly and stably. Further, the drive stud 110 of thetool 10 is closely secured on the mounting portion 211 and cannot berotated relative to the main body 21 of the tool display rack 20, sothat the drive head 11 of the tool 10 is rotated relative to the mainbody 21 of the tool display rack 20 to test the rotation angle of thedrive stud 110 of the tool 10 exactly. Further, the passage 220 of thepressing member 22 has a side having two ends each formed with anoblique limit portion 221 to increase the testing travel of the tool 10,so that the rotation angle of the drive stud 110 of the tool 10 istested more exactly.

Referring to FIG. 7, the tool display rack 20 further comprises anattachment 214 detachably mounted on the main body 21 and integrallyformed with the mounting portion 211, the locking portions 212 and theretaining portions 213. The main body 21 is formed with a positioninghole 216 for mounting the attachment 214 and two opposite locking holes217 located beside the positioning hole 216. The attachment 214 has aperiphery formed with two opposite locking stubs 215 each locked in arespective one of the two opposite locking holes 217 of the main body21, so that the attachment 214 is secured on the main body 21 closely.
